APPARATUS FOR EMPTYING RECEPTAGLES.

Specification of Letters Patent.

Patented (lot. 29, 1913.

Application filed February 3, 1917. Serial No. 146,509.

To all whom it may concern:

Be it known that I, JOHN W. Cox, a subject of the King of Great Britain, having declared my intention of becoming a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented'new and useful Improvements in an Apparatus for Emptying Receptacles, of which the following is a specification.

This invention relates to an apparatus for emptying receptacles and consists in certain improvements in the construction thereof as Wlll be hereinafter fully described and pointed out in the claims.

The object of the invention is to provide a simple and eflicient means for emptying re- It is particularly advantageous in emptying receptacles in which castings are annealed in forming malleable castings. Here the mass formed by the annealing material and the castings can only be loosened by subjecting the receptacle to considerable shock. The separation of the castings from the residue of the annealing material is also desirable. t

The invention is illustrated in the accompanying drawings as follows Figure 1 shows a side elevation of the apparatus.

Fig. 2 an end view from the right of Fig. 1.

1 marks a tilting frame which is pivotally mounted by means of a hinge 2 upon a base 3. Shafts 4 are journaled in bearings 5 on thetilting frame. The shafts 4 have the supporting pulleys 6 in which tracks 7 on the drum 8 travel. This arrangement of shafts as 4 with the pulleys and track is a common form of mounting for rotating drums.

A frame 9 is supported on the posts 10 extending upwardly from the frame 1 and a motor, preferably an electric motor 11 is mounted on the frame 9. The motor drives a pulley 12 and a pulley 13 is driven from the pulley 12 by a chain or belt 14. The pulley 13 is mounted on a shaft 15 and the shaft 15 is carried by bearings 16 on the frame 9. A pulley 17 is mounted on the shaft 15 and drives a pulley 18 by means of a belt or chain 19. The pulley 18 is mounted on a shaft 20 and the shaft 20 is mounted in bear ings 21 arranged in brackets 21 extending from the posts 10. A pulley 22 is mounted on the shaft 20 and drives by means of a chain or belt 23 a pulley 24 ononeof the arm with a rod 45.

shafts 4. In this manner the drum is rotated. The tilting of the frame 1 does not break the driving connection.

It is desirable to have a charging device for the receptacles and I have provided a charging platform 25. It is pivoted at 26 on a bracket 27 extending upwardly from the base 3. The platform has two faces, the face 28 being in a horizontal position with the platform in its lower position and the face 29 with the platform in elevated position. The face 28 with the platform in the lower position is flush with the floor so that the re- ,ceptacles may be readily moved upon it and the face 29 is in alinement with the opening in the drum so that the receptacles can be readily moved from the platform into the drum. Any convenient means of elevating the platform may be used but I prefer a fluid actuated hoisting device for this purpose. A cable 31 is secured to the platform and eX- tends over the pulleys 32 and 33. The pulleys 33 are carried by a rod 34 secured to a piston 35. The piston 35 operates in a cylinder 36. The cylinder and the pulley 32 are mounted on a frame 37 carried by the posts 38. A pipe 39 supplies the cylinder 36 with fluid. This pipe is carried to a control platform or station 41 and is there provided with a controlling valve 40. The op eration of the hoist is apparent. WVhen the fluid is turned into the cylinder, it moves the piston, carrying with it the pulleys 33 thus drawing up the cable 31 and with it the platform 25.

Inorder to move the loaded receptacles from the platform to the drum a sweep 42 is provided. This is in the form of a swinging The rod 45 is secured to a piston 46. The piston 46 operates in a cylinder 47. The cylinder 47 is carried by a frame 48 supported on the posts 38. A pipe 49 carries fluid to the cylinder. This pipe is carried to the control station or platform -11 and is there provided with a controlling valve 50. The operation of this feature can be readily understood. When the platform has been elevated it brings the receptacle to the position shown in dotted lines in Fig. 1 with the sweep 42 to the rear of the recep- .tacle. When fluid is admitted to the cylinder, it moves the sweep forward, carrying wlth 1t the loaded receptacles and moving them into the drum.

ing the supporting frame. The frame has station or platform 41 and is provided with a controlling valve 59. When the fluid is exhausted the frame 1 drops by gravity, thus tilting the drum. When the drum is in operation, the platform is held in its upper position by turning fluid under the piston 55 soas to hold the frame 1 in its upper or horizontal position.

The drum has openings 60 through which the refuse material which is contained in the.

receptacles may pass. In order that very severe shock may be given to the receptacle the interior of the drum is supplied with ribs 61 ordinarily formed of railroad iron and extending longitudinally ofthe drum.

As the drum is rotated the receptacles 30 are subjected to very severe shock so that the material such as annealed castings are entirely loosened from the receptacleand to some extent the receptacles are emptiedin the drum itself. The rolling of the receptacle in th rotating drum accomplishes this loosening to some extent but this is accentuated by the use, of the projections or ribs which not only assures the rolling of, the receptacle in the drum but also localizesthe blow on the sides ofthe receptacle as it rolls. The receptacles are cleared of'rcfuse material and this passes out of the openings in the drum. When the castings are entirely loosened the drum is tilted, thus emptying the castings and the receptacles from the drum. In this manner the emptying of the receptacles is very easily accomplished.

What I claim as new is 1. In an apparatus for emptying receptacles, the combination of a drum'open from end to end to permit the passage of a receptacle through it and having a receiving end to receive a receptacle and having an unobstructed discharge opening to permit: the discharge of a receptacle by gravity when thehdrum is tilted; a mounting forth'e drum; means for rotating the drum; and-means for tilting the drum to give to the drum an inclination to discharge material from the discharge end of the drum by gravity.

2.
